Water Methanol Injection
Worried of overheating engine due to lean air mixture, or engine knocking due to
early detonation.Well there is a solution to overcome all this problem.
People had been developing Water injection technology for cars to reduce the intake air
temperature.Water is known for its high latent heat of vaporization, so it can absorb the
heat and cool down the intake air temperature.It also have the same effect of a higher octane fuel where it wont detonate easily thus we can feed more air fuel mixture into the combustion chamber
The basic principle is simple.Water is injected in the air intake ram before the throttle body.
However the injected water should be a fined atomized particle so it will be evaporized by
the hot intake air.This is to avoid accumulation of water drops in the engine which will
disturb the combustion. The fined atomization can be achieved by aplying high water pressure to a suitable nozzle.We can see this example of this system in our local mamak store where they spray fine water mist in front of a fan.We can barely feel the water as it is very fine.
Position of the nozzle placement
The a main advantage of this system is we can achieved more power with the same engine configuration.
For turbo powered car, we can increase the boost pressure to a higher level without worrying of engine damage.Even if the air fuel mixture is lean the temperature of the air fuel mixture is cooled down by the the water injection
As for Naturally Aspirated car (NA) we can retard the ignition so we can have more air fuel mixture in the combustion chamber without worrying of early detonation which will cause engine knocking.
For additional power, Methanol can be added to the water.It is usually 50-50 ratio.It can boost up the combustion similar to your NOS system
In addition, we can save fuel by using this system as we can introduce a leaner air fuel mixture to the engine without worrying of damage.Cold intake air will also make the engine more efficient.Just compare between driving at noon and driving at night.
Basic System Without The Use Of Pump And Nozzle
Water Injection system can be installed at any shop which sells and provide installation of this system whichyou can found by browsing in forums or website such as www.zerotohundred.com and www.lowyat.net. If you have the initiative knowledge and skill you can actually diy you own system.Resources can be found all around the net and also youtube.com.But you have to take your own risk of doing it.

Example Of this system which is also used by some accesories and workshop in Malaysia is Snowperformance
Any comment,question and discussion is welcomed.I will try my best to answer and discuss.
